I’m trying to read the file path from tkinter in the panda3d window. But it doesn’t work, is it possible to open tkinter window in panda3d?
The code:
import os
from direct.gui.DirectGui import *
from direct.showbase.ShowBase import ShowBase
from panda3d.core import *
from tkinter import *
from tkinter import filedialog
class MyApp(ShowBase):
def __init__(self):
ShowBase.__init__(self)
self.cam.setPos(0, -20, 0)
self.jack = self.loader.loadModel("models/jack")
self.jack.setHpr(0, 180, 180)
self.jack.reparentTo(self.render)
bk_text = "This is my Demo"
textObject = OnscreenText(text=bk_text, pos=(0.95, -0.95), scale=0.07,
fg=(1, 0.5, 0.5, 1), align=TextNode.ACenter,
mayChange=1)
def setText():
bk_text = "Button Clicked"
textObject.setText(bk_text)
def btn():
path = os.getcwd()
folder_selected = filedialog.askdirectory()
print(folder_selected)
b = DirectButton(text=("OK", "click!", "rolling over", "disabled"),
scale=.05, command=tkinter)
def tkinter():
window = Tk()
window.title('P3DFormatConversion')
window.geometry('500x300')
folder_selected = filedialog.askdirectory()
print(folder_selected)
window.mainloop()
app = MyApp()
app.run()
Thank you for your reading.

Your code works fine for me; clicking the DirectButton makes the directory selector pop up, and choosing a directory makes it printed to the console.
What exactly do you mean by “doesn’t work”? Also, on which OS are you?
I’m using macOS Monterey 12.1, python 3.8, and Panda 1.10.9.

On macOS you need to put want-tk true in Config.prc to make Tkinter play nice with Panda3D, I believe.

Thanks for your reply.
Is it something like this?
Well… I use some other method to call out the tkinter window. However, it is not the perfect solution.
Move the tkinter function into tkinter.py
change the tkinter function contexts to this:
def tkinter():
os.system("python3 tkinter.py")

loadPrcFileData("", "want-tk true") should also work, but it’s important to do it before ShowBase is initialized. You should probably also use base.tkRoot then rather than creating your own Tk root.
Of course, a subprocess works as well.

I don’t understand how to use base.tkRoot.

Just this:
window = base.tkRoot
I also think you don’t need to call window.mainloop(), Panda will handle this.
As for the Pmw error, you need to install the Pmw package, you can do this by typing python3.8 -m pip install Pmw (or however you invoke your Python interpreter).

Thanks for your reply rdb.
It seems to work. But there will pop up a tk window in the beginning. How to remove the left-up tk window?
I change my code:
def tkinter():
window = base.tkRoot
window.withdraw()
folder_selected = filedialog.askopenfilename()
print(folder_selected)
In fact, there is no need for a Panda window here, you need to create an application without a window and embed the panda context in Tk. There are many examples of this on the forum, use the search to find it.

I really don’t think that’s a good idea, I would advise against parenting the Panda window to the Tk window unless you actually need to do this.
I think calling withdraw() is the way to hide the root window. Is that not working for you?
